Abstract:
The PICosecond subMICron (PICMIC) is a new detection concept that intends to simultaneously exploit the remarkable intrinsic spatial and time precision of the MicroChannel Plate (MCP) detectors. PICMIC is based itself on two new concepts. The first is similar in principle to the one used in the GPS and allows, with a limited number of electronic channels, to obtain a precise measurement of the arrival time of particles crossing the MCP. The second, conceived to measure the position of these particles, uses tiny pixels that are interconnected in an original way. The new scheme leads to an excellent granularity without suffering from the usual ambiguity encountered in the strip-based readout systems. The new system is operated with a smaller number of electronic channels with respect to a pixel-based readout one.
Both the spatial and the time measurement systems were individually tested and validated before to be assembled in a first prototype. The prototype equipped with an alpha source allowed the validation of the whole concept. We present in this seminar the PICMIC concept, the realization of the measurement systems as well as the first results obtained with the prototype. We discuss also the development of a new generation of MCP we call NanoChannel Plate (NCP) which intends to improve the time and spatial resolution by at least one order of magnitude. Such a new device could be fully exploited thanks to the PICMIC concept.
About the speaker:
Imad laktineh is professor at the University of Lyon and senior researcher at the Institut des deux infinis de Lyon (IP2I). His main activities are on detector R&D for the experiments of future high-energy colliders (HL-LHC, ILC, CEPC and FCCee ). He developed the concept of the Semi-Digital Hadronic Calorimeter SDHCAL and led the construction of the first technological prototype of the CALICE collaboration using this concept. He is currently working on including the time information in this concept (T-SDHCAL) to improve on the Particle Flow Algorithms (PFA) techniques. He also initiated the CMS- iRPC project proposing a new RPC readout concept. He has recently invented the PICMIC concept that intends to fully exploit both the excellent spatial and time resolutions of the MCP devices. In parallel, he is developing similar devices with much better performances named NCP for NanoChannel Plates.
Pr. Laktineh is very active in the new DRD collaborations with leading roles in DRD1(gaseous detectors), DRD4 (photo-detection) and DRD6 (calorimetry). He is currently the scientific adviser of the CNRS-I2P3 for innovative detectors and quantum technologies.
